Biomechanics Newton’s Laws of Motion
First Law – Law of Inertia (momentum): An object at
rest will remain at rest unless acted upon by an outside force. An objectin motion will remain in motion unless acted upon by and outside force. Important Points: Force is required to change the state of an object’s motion Objects in motion tend to remain in motionBiomechanics Newton’s Laws of Motion
Second Law – The Law of Acceleration (force): When force is applied to an object the acceleration that the object experiences will be proportional to the force andinversely proportional to the object’s mass. Important Points: Large forces are needed to produce high rates of acceleration Objects that are large require substantial forces to cause them to move

Third Law – Action and Reaction: For every force that is produced a second force, equal in magnitude and opposite in direction is also produced. ImportantPoints: Forces result in “reaction” forces that act on the body Movements of one part of the body produce “counter-movements” in another part of the body
